My LO is 7 weeks old today, and she on Similac Sensitive formula, I also give her gripe water and probiotics once a day. She normally drinks 27 oz a day, yesterday she spit up/threw up about 30 min after eating and drank only 21 oz for the day, today she has done it twice and is at maybe 17 oz for the day.. she was eating 4 oz each feeding and now it is maybe 2 oz... I have a doc appt tomorrow but any help would be appreciated since I am a first time mom and I am worried something is wrong and I don’t know what to do to fix it right away...
